AUTOMATlC OILER FOR VEHICLE-WHEELS.

S?ECIFICATION forming part of Letters Patent o. 655,518, dated August 7', 1900. Application filed June 26, 1900. Serial No. 21,679. (No model.)

To @ZZ whom t jnayconccrn:

Be itknown that I, VAN DON ROE, a citizen of the United States, residing at Maury Oity, in the county of Crockett and State of Ten` nessee, have invented certain new and useful Improvements 'in Automatic Oilers for Vehielo-Wheels; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in automatic oilers for vehicle and other wheels; and it consists in attaching an oil-cup to the hub of the wheel with cornmunicating passage-way from the cup to and through the boxing of the wheel and in the provision of a plunger which is mounted in suitable guideways within the oil-cup and adapted to reciprocate as the wheel rotates, the inner end of the stern of the plunger working in the contracted or nose end of the cup, thus forcing asupply of oil by the frictional contact of the circumference of the stem with the inner surface of the contracted end of the cup to the inner surface of the boxing against which the shaft turns.

More specifically the invention consists in an automatic oiler for wheels comprising a cup attached to the hub and communicating with the interior of the box of the wheel and having a weighted plunger mounted in suit; able guides and the provision of springs against which the plunger strikes as it reciprocates for the purpose of breaking the force of the weighted plunger and making the working of the same noiseless as the wheel rotates.

My invention will be hereinafter more fully described, and then specifically defined in the appended claim. The device is fully illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which- Figure lis a vertical sectional view through my improved oiler, shown as attached to the hub of a wheel, a portion of the hub being shown in cross-section. Fig. 2 is a cross-sec'- tional view through the oiler.

Bheld in place.

Reference now being had to the details of the drawings by letter, A designates the hub of a vehiclewheel of any desired construction and B are the spokes mortised in sockets therein. At any suitable location between two of the spokes a hole is bored from the outer to the inner circumference of the hub and through the boxing C, seated Within the hub., The bore of the hole through the casing of the boxing is screw-threaded, as seen at C', and the oil cup or receptacle D is fitted with its nose D, which is contracted, in the hole thus bored in the hub, while the threaded portion on the outer circumference of the nose of the cup is screwed into the threaded bore in the boxing, whereby the cup is securely The tapering portion of the end of the oil-cup should fit, when adjusted in place, against the tapering wall of the hole bored in the hub. The outer end of the cup is provided with a cap E, having screw-threaded connection with the cup, as shown.

Secured to the inner wall of the cup are the spider-braces F and Gr, a top plan view of one of which is shown in Fig. 2. As will be observed, these braces have three arms and a central aperture. The plunger K, which may have a threaded and detachable head K', has its central or middle portion enlarged, forming a weighted portion K2, with shoulders 7c. The portions of the plunger-stem projecting beyond each end of the weighted center pass through and are guided in the apertures in the spider-braces F and G. On the brace F is mounted a coil-spring N about the bore in said brace, and against this spring the inner end of the weighted portion of the plunger is designed to strike to break the force of the plunger as it falls by gravity toward the hub. The inner end of the plunger-stein should iit snugly the bore of the nose of the cup, and as the stem reciprocates in the revolving of the wheel the oil is fed forward by the two contacting surfaces of the inner wall of the noso of the cup and the outer circumference of the stem. On the face of the spider-brace G nearest the brace F is fastened a second coiled spring M, against which the outer end of the weighted portion of the plunger-stem is designed to strike when the plunger is thrown out either by centrifugal force or by gravity, thus breaking the force of the throw and making the working of the plunger in its reciprocations noiseless.

The receptacle or cup being filled with oil, it will be observed that the turning surface lof the shaft will be constantly kept lubricated by the plunger working back and forth through the nose of the cup.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is

An automatic oiling device 'for Vehicle- Wheels, comprising an oil-receptacle, spider braces or guides secured to the inner wall of the receptacle and centrally apertured, coiled springs seated on the adjacent faces of said braces or guides, a reciprocating plunger passing through the apertures in said braces or guides and having aweighted middle portion, the ends of which are adapted to strike against said springs as the plunger reciprocates, the inner end of the plunger Working constantly in the nose of the receptacle and in contact with its inner wall, as shown and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
